v3:
remove unused includes
fix status ops
fix from Fengguang Wu
for Kbuild test robot: symbol 'stm32_reset_ops' was not declared. Should it be static?
use 'builtin_platform_driver' instead 'postcore_initcall'
v2:
Don't use reset-simple driver but a custom reset driver.
add dt-binding documentation.
This patch-set enables the reset of STM32MP1.
STM32MP1 reset IP has a register to assert by writing '1' and another
register to de-assert by writing '1'.
The patch 'dt-bindings: reset: add STM32MP1 resets' could be squashed
with the patch:
'dt-bindings: Document STM32MP1 Reset Clock Controller (RCC) bindings'
commit 3830681d354f
